- To all whom it may concern:

-Be it' known that I, WILLIAM ZA-BnL, a

' citizen of. the- United Statesyresiding at Edgewood borough, in the county of Allegheny and State'of Pennsylvania, have -1n-' vented"certa-in-new and useful Improves 'ments in Printing-Telegraph Apparatus, of

i which 'fzollowing 1s a specification.

'My 'inrention relates to printing tele graphapparatus, 'and'particularly to the translator comprised. in such apparatus.

, willjdescribe one form of translator embo'dyingfmy invention, and will then point j out the novel features thereof in claims.

Referring first to Figs. 1 and 2, the referenoe character F designates a frame comprising a bottom plate 1, a platform Qjand'other suitable structural parts. Mounted on the bottom plate 1 is an electric motor M whose rotatable member is connected with a. spindle 3 on which is fixed a spiral gear wheel 4. This gear wheel mesheswith and drives a -spiral gear wheel 5 which is fixed Specification ofL'etters Patent.

17 respectively for purposes which will hereinafter appear. nected with theshaft is'a bar (see Figs. 5- and 6) which actuates the. printing mechanism as hereinafter explained.

Shaft 10i's at times connected with gear wheel 5' by means of a; ball'clutch C which referring to Figs. l gand I will now explain, 2. This clutch. comprises a shell 45 formed as an extension of the hub.- of'gear wheel 5, and a clutch plate 46 securedto theshaft l0 and located within the shell. 45. The periphery of clutch plate-.46. is provided with a-plurality of triangular notches 49 in each of whichislocated a ball 48. 'Eachball is acted uponby' a spring. 50 which-is lnafter' explained. Gear wheel5 rotates'in.

Also eccentrically con- I seated -in. a' hole in the'clutch plate-and which tends-to force the ball outwardlyso' that it will wedge between the-clutch plate and the shell 'andso clutch the two together.

disk '51, loosely mounted on clutch plate 46, carrying a number of projecting studs 47, which, when the disk -51 is held against rotation, press against-"and stop the balls, the

troniagnet' 38 mounted on the platform 2,-

for which purpose the diskis provided with a'lip 91*Which is engaged by a hook on the vertical arm of a pawl 54 pivotally mounted in a lug 55 (in bearing '11. Resting on the horizontal 'arrnJof this pawl-*isa stem- 53 which carries a clam 53 by means of which the stem may. be pressed downwardly y, armature.f 52 of magnet 38jwhen 'the magnet is energized". llawl' 54 is ac't'edupom bya spring 56 attached to hearing 1-1, which tends to hold it i-nposition to engage the lip 91-, but when magnet 38 is energized, armature. 52 swirigs the pawl-outwardly. against the action of the springv so that disk 51- is released. Armature 52 is-pivote'din a magnet bracket 38, audits upward movement is limi'ted by a stud 57which is screwed intov the bracket 38 and passes through a hole in the armature and carries nuts 57 by which thelarmatnre is stopped.- Itwill be seen that theclutch is engaged or not, accordingas the disk'51 is free to rotate or is held by pawl 54. p In the operation of the apparatus it is desirable that shaft should ma he only one 1"ei-olui ion 'at a time; "magnet 3 is, there fore, magnetized only momentarily, that before shaft 10 has made a'complete re -ol;ution, pawl 54: has returned to position for engagement, with lip -91'and the shaft is 4 then stopped. When .disk 51 is arrested by pawl 54. the springs 50 are compressed, and since these. springs are mounted in" clutch plate 46' the reaction against'ball's 48 and studs 47 would cause the clutch plate to rotate inthe reverse direction and rengage,

- were no means provided to check this reverse rotation. I therefore provide a single tooth ratchet 58 fixedto the shaft and adapt ed, to be engaged by pawl 59 due to the tension ofs'pring 60, Paw159 is'adjusted so as to engage-the tooth or ratchet 58 at the point at which the energy" oft-he rotating pa'rts has been absorbed by the springs 50. The shaft 10, therefore, when at rest, is held in a definite position-between pawls 54 and 59, and when disk 51 is released, the

engagement of the clutch is rapid and positive due. to the tension of springs 50.

- B, B, etc, are six permutation bars, one of which is shown in detail in Fig. 9, which bars are mounted in the following manner "-to reciprocate longitudinally. Fixed on the platforn'f2 is a post 18 (see Figs. 1, 4 and (l) to one side. of which a guide plate 19 is secured by, bolts 20. This guide plate projectsfrom the post 18 and is provided with a rectangular hole through which the permutation bars B slide. separatedby a comb 21- having a slot for each bar, which comb is attached to the other side of the post 18 by the bolts 20. Each bar rolls on a ball 24 which located between the bar and the post 18 and'is kept in place by the plate '19 and the comb 21 as shown in Fig. i. The longitudinal movement of each bar is limited by a plate 22 which is clamped to the comb 2i by nuts and which projects into a slot cut in each bar.

The bars B are further supported and guided by another post 18 (see l igs. 7 and 8) mounted on platform '3 near the other end, and also bya middle post 18 (see Figs. 2 and 8). Post 18 is proli ided with its corresponding driving spring 31 which i s-under'tension and which The bars are parts similar to those shown on post 18 except that the plate 22 for limiting. the

reciprocation of the hers is not duplicated.

The bars B are selectively controlled and reciprocated-by apparatuswhich I will'now describe. Mounted on the platform 2 is an end plate 9 to which is attached a plate 9.

Fixed on the plate 9 are six selector magnets S, one for each permutation bar each" of which magnets controls an armature 25 (see Figs. 3 and at). These magnets are controlled by any desired mea-ns, the usuallneans beinga sun-flower? or commutator connected with a telegraph line.

by a spring 25, and carries a finger 26 which; engages with one arm of a release pawl. 97,

Each armature 25 is biased to the open position one pawl being provided for each 'magnet. Thereleas'e-pawls 27' are mounted on a shaft 28, which is fixed in a yoke 32 mounted on trunnions 33 in two lugs 35 projecting from the end plate 9. Integral-with yoke, 32 is .a crank arm 32 in the end of which is journaled the roller 17 which coacts with.

cam 151alnd by means of which the yoke 32 may be rocked. The yoke 32 alsojcarries a shaft 30 on-which are journale'd six driving pawls 29, one for each permutation bar.

Each dliving pawl comprisesone arm 29' which coacts with a. hook 36' on one of the release pawls2], and another arm 29 which is adapted to swing into a notch 37 in the end of't'he corresponding permutation bar- Each release pawl 2-7 is connected with pawl 29 by a therefore performs two'functions,- viz.-, to

bias the pawl 29 toward the operative"- position in'the notch 37 on thecorresponding permutation bar, and to' biasfthe'paWL 27 toward such. position that its hook 36,

holds-the pawl 29 in the inoperative pos'ition'out'o'f the permutation bar notch.

It will be seen that if one or more of the pawls 29 are unlatched and the yoke 32 is then swung by cam 1.5, the' corresponding bar or bars B will be moved to the right as viewed in Fig. if During this movementin which is igurnaled the roller 16 which coacts with cain 14.

The yokes 3-2 and 39 are biased to the positions in which they are shown by means late- 9 V Integral withthe yoke 39 is a crank arm 39".
